FEED-WATER. HEATER.

Specification of Letters Patent.

Patented Jan. 17, 1911.

Application filed November 25, 1910. Serial No. 593,989.

lb all whom it may concern:

Be it known that I, EDsVARD T. TURNER, a ci'izen of the United States,residing at Dayton. in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Feedater Heaters; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon. which form a part of this specification.

This invention relates to improvements in feed water heaters, andpossesses the new and useful features hereinafter described inconnection with the accompanying drawings and pointed out in the claims.

The objects of the invention are several, principally among which is theprovision of a more economical compact and efiicient feed water heater.

With this end. in view, the improvements relate specifically to aninterior construction of the device by means of which the oil isseparated from the steam in a separator, and is retained in a separatedcondition and caused to pass from the apparatus with the overflow waterin the bottom of said apparatus.

The improvements further consist in the provision of a waterseal-overflow which is cast with the heater shell and is contained onthe inside of the heater.

The improvements further consist in the provision of means whereby easyaccess may be had to the precipitating pans or trays for cleaning, andeasy access may be had to the tiller in the lower portion of theapparatus.

()ther advantages are attendant in my improved feed water heater, suchas cheapness in construction and a reduction in weight due to therebeing fewer castings and less machine work necessary in completing thesame ready for installation, as will more fully appear from thefollowing description taken in connection with the accompanyingdrawings.

In said drawings Figure 1 is a perspective view of the apparatus showingthe precipitating pans or trays swung outwardly. Fig. 2 is a vertical,longitudinal, mid-sectional view on the line 0 c of Fig. 2. Fig. 3 is asection on the line oa of Fig. 2. And Fig.

at is a sectional View on the line Z)b of Fig. 2.

Similar reference characters denote the same parts in the specificationand drawings.

Cast on the interior of the heater 1 is a chamber 2 in which an oilseparator 3 is placed, said separator being suspended in said chamber bymeans of a flange 4. The steam conducted from the boiler (not shown) isintroduced into this separator more or less commingled with oil. Toseparate this oil and get it out of the apparatus so that it may not becarried by the steam, in any objectionable amount, to the water enteringthe apparatus, it will be understood, is desirable. The steam inlet maybe so arranged that the steam will enter at the top or side of theapparatus. In the drawings the entrance is shown at the top.

Around the upper portion of the separator 3 is a series of steam ports 5which communicate with the surrounding chamber 2 and with a down chamberor steam leg 6 in the back and on the interior of the apparatus. Thischamber 6 is inclosed between the back of the apparatus and an interiorwall 7, which is provided with suitable ports or openings 8 constitutingoutlets for the steam to the precipitating pans to be presentlydescribed. The lower end of the steam chamber 6 is inclosed by ahorizontal baille wall 8*, and below this wall are two chambers 9 and 10formed by extending downwardly a wall 11 from the wall 8*. The wall 11terminates at a suitable point above the bot tom of the chambers 9 and10, so as to allow free communication from the first of these chambersto the other. These chambers form a water seal to prevent the heaterfrom blowing up, due to an excess of steam pressure which may occur inthe heater, and also serves as an overflow for the excess watercontained in the bottom of the heater. The oil and water are alsotrapped in these chambers, first entering chamber 9 through a down pipe12 and filling up both chambers until it rises to the outlet 13 throughwhich it passes from the apparatus. The pipe 12 extends from the bottomof the oil separator 3 into the initial chamber 9. The inner wall let ofthe chamber 9 separates said chamber from the filtering chamber 15 byextending it a substantial distance above said filtering chamber.

The precipitating pans or trays 16 are lo cated within the apparatus,each individual pan being arranged below a respective steam port 8. Eachof these pans has a portion of its marginal rim removed as at 16 inorder that the water may flow from one pan to the other. The portion ofeach upper pan where the rim is removed, lies above the rim portion ofthe adjacent lower pan, so that the water flows from one pan to theother across the face of each pan. The precipitating pans are hinged intwo series so that they may be swung out of the apparatus as in Fig. 1.One series of pans may be joined by a wall 17 in which case they aremade a single casting. This series of pans are hinged to a rod 18, whichprojects through a suitable number of cars 19 extending from the wallsat one of the front corners, see Fig. 3. This series of pans arerecessed as at 20, so that they may be swung out of the apparatus andaround the corner, as in Fig. 1. The other series of pans may be castintegral with the door 21, or they may be supported on the door byattaching them in any suitable manner. Each series of pans are so spacedor arranged relative to each other, that when they are swung into theapparatus they nest one below the other as in Fig. 1. It is possible tohinge both series of pans in a similar manner, in which case neitherseries would be mounted on the door The inlet water pipe 22 enters theupper portion of the apparatus and delivers the water to a receptacle23, which overflows at its margin and delivers the water to theuppermost precipitating pan from which it traverses throughout theseries. From the lowermost precipitating pan the water flows to theapertured plate 24E just above the filtering chamber. From the filteringchamber the water, free from mineral matter, flows to the chamber 25 inthe extreme lower end of the apparatus from whence it is conducted tothe place of consumption.

Having described my invention, I claim: 1. In a feed water heater, acasing having a steam chamber in the upper portion thereof, a down steampassage extending therei from inclosed on its inner side by an aperturedwall, and water seal-overflow chambers in the lower portion thereof, anoil separator located in the steam chamber in the upper portion of thecasing, said separator having orifices in its upper portion throughwhich the steam enters said steam chamber and passes therefrom into thedown steam passage and thence through the apertured wall to the interiorof the apparatus,

and an oil pipe extending from the oil separator into one of the waterseal-overflow chambers, substantially as specified.

2. In a feed water heater, a casing provided with a steam chamber in theupper portion thereof from which extends a down passage in the rearportion of the casing, said down passage being inclosed on its innerside by a wall having openings therein, a bafile wall inclosing thelower end of said down passage, a space belowsaid baflie wall dividedinto two communicating water seal-overflow chambers by a lower wallprojecting from said baflie wall, an oil separator located within thesteam chamber in the upper portion of the casing, a pipe extending fromsaid separator to one of the water sealoverflow chambers, and a seriesof precipitating pans mounted relatively to the openings in the wallforming the inner inclosure of the down passage, substantially asspecified.

3. In a feed water heater, a casing having a steam chamber in the upperportion thereof, and a down passage leading therefrom, said down passagebeing inclosed on its inner side by a perforated wall, and two series ofprecipitating pans having hinged connections adapting them to be swungin and out of said casing, the pans of one series being adapted to liebetween the pans of the otherseries when in position, said pansoccupying positions relatively below the openings in the wall formingthe inner inclosure of the down passage, substantially as described.

4. In a feed water heater, the combination of a casing having a steamchamber in the upper portion thereof, and a down passage leadingtherefrom inclosed by an inner perforated wall, two series of swingingprecipitating pans adapted to occupy positions relatively below theopenings in said perforated wall when in their inner positions, twocommunicating water seal-overflow chambers in the lower portion of saidcasing, separated fro-m the down passage by a horizontal wall, an oilseparator within the steam chamber in the upper portion of the casing,and a down pipe extending from said to one of the water seal-overoilseparator substantially as described.
